Objectives : The purpose of this study is to report two cases of improvement in meniscal injury induced knee pain after M.S.T(Motion Style Treatment). Methods : Two patients diagnosed as meniscal injury were improved by M.S.T(Motion Style Treatment). This study was measured by Numerical Rating Scale(NRS) score and physical examination. Results : In this study, in the end of continuous M.S.T(Motion Style Treatment), patient's knee pain had improved. Numerical Rating Scale(NRS) were also decreased. Conclusions : As seen in this two cases of patients of knee pain who were diagnosed as meniscal injury, M.S.T(Motion Style Treatment) has a positive effect to control pain with knee pain who are diagnosed as meniscal injury.

To investigate the diagnostic accuracy and applicability of barium enema(BE) and rectal suction biopsy with acetyl cholinesterase(AChE) histochemistry in the diagnosis of neonatal Hirschsprung's disease(HD), we retrospectively reviewed the findings of BE and AChE staining in 96 neonates with suspected HD during a 10-year period from January 1991 to December 2000. Sixty-nine cases of HD(58 males and 11 females) and 27 cases of non-HD are included in this study. In regard to BE, HD was based on definite transitional zone, suspicious HD on reversed rectosigmoid index(RSI <1), and non-HD on normal RSI(RSI>1). The histochemical criterion used for the diagnosis of HD was that of Chow et al(1977), i.e., the presence of many coarse discrete cholinergic nerve fibers in the muscularis mucosae and in the immediately subjacent submucosa regardless of infiltration of cholinergic nerve fibers in the lamina propria. Of 66 neonates with HD who underwent BE, transitional zone was identified in 33 cases(50 %) and reversed RSI in 19 cases(21 %), microcolon in 4 cases and normal finding in 10 cases(15 %) while of 27 neonates with non-HD, there was normal finding in 16 cases and reversed RSI in 9 cases(41 %). Thus diagnostic accuracy based on transitional zone was 64 %. The positive predictive value of reversed RSI for the diagnosis of HD was 68 %. Of 42 neonates with HD who underwent AChE histochemistry, there were 41 AChE-positive reactions and one AChE-negative reaction in a neonate with total colonic aganglionosis, while of 27 cases of non-HD, there were one equivocal AChE-positive reaction and 26 AChE-negative reactions. Thus AChE histochemical study showed a 97 % diagnostic accuracy with a 98 % sensitivity and a 96 % specificity. In conclusion, we believe that BE is valuable as a first diagnostic step since about 80 % of neonates with HD show significant radiologic findings such as a transitional zone or reversed RSI. AChE histochemical study was a more reliable diagnos tic tool showing a 97 % diagnostic accuracy, and is part.

Objectives : The purpose of this study is to investigate the latest trends of korean Medicine treatments on traffic accident for recent 5 years. Methods : We investigated the studies on korean Medicine treatments for traffic accident via searching 6 Korean web databases. As a result, 65 research papers were found to be analyzed according to their published year, the titles of journals, the types of study, the number of cases, the sites of injury, the types of treatments the instruments for assessment and ethics approvals. Results : 65 articles were published since 2008. The studies on korean Medicine treatments about traffic accident were mainly published in Journal of Oriental Rehabilitation Medicine. 10 case studies, 14 case series, 11 non randomized controlled trials, 21 randomized controlled trials and 9 systemic reviews had been under research. The most frequently occurred symptoms were neck pain and low back pain. In most studies, various korean Medicine treatments were used to treat the symptoms. Visual analogue scale(VAS) and neck disability index(NDI) were used as primary assessments. In most clinical studies, there were no mention about approval of institutional review board(IRB). Conclusion : In this study, we analyzed the trends of korean Medicine treatments on traffic accident from 2008 to 2012. Reviewing the domestic trends of studies on korean Medicine treatments for traffic accident and examining the strong and weak points of those treatments are essential for the future studies. It is needed to adopt the qualitative methods of evaluation in order to develop a level of evidence.
Electronic Properties of MIM Structure Organic Thin-films that Manufacture by LB method

전기 전자 소자를 제작하는 방법으로 Langmuir-Boldgett(LB)법이 많은 관심을 받고 있다. 수면위에 형성된 단분자막을 압축 또는 확장하면, 분자가 배향하는 과정에서 맥스웰 변위전류(MDC)가 흐른다. MDC는 전속밀도의 변화에 기인해서 흐르므로 MDC를 측정하는 것에 의해 분자의 동적 거동 관찰할 수 있다. 단분자막을 압축하는 속도와 분자면적은 서로 선형적인 관계를 갖고 있다. 본 연구에서는 압축속도를 30, 40, 50mm/min으로 달리하여 단분자막의 동적 거동을 관찰하였으며 LB법을 이용하여 Arachidic acid 단분자를 slide glass 위에 Y-type으로 9$\sim$21층의 다층막을 누적하여 Au/Arachidic acid/Al 소자를 제작하였다. 또한 Metal-Insulator-Metal(MIM) 소자의 I-V 특성을 측정하여 전극간의 거리가 커질수록 절연특성이 좋아짐을 확인하였다. The Langmuir-Blodgett(LB) technique has attracted considerable interest in the fabrication of electrical and electronic devices. Maxwell displacement current (MDC) measurement has been employed to study the dielectric property of Langmuir-films. MDC flowing across monolayers is analyzed using a rod-like molecular model. A linear relationship between the monolayer compression speed u and the molecular area Am. Compression speed a was about 30, 40, 50mm/min. Langmuir-Blodgett(LB)layers of Arachidic acid deposited by LB method were deposited onto slide glass as Y-type film. The structure of manufactured device is Au/Arachidic acid/Al, the number of accumulated layers are 9$\sim$21. Also, we then examined of the Metal-Insulator-Metal(MIM) device by means of I-V. The I-V characteristics of the device are measured from -3 to +3[V]. The insulation property of a thin film is better as the distance between electrodes is larger.

계산과학은 과학이나 공학 분야의 문제에 대하여 수치해석과 컴퓨터 계산을 이용하여 해결하는 방법을 연구하는 학문이다. 계산과학은 기존의 형식적인 수학, 과학적 모델을 통한 해결이 불가능한 문제에 관하여 컴퓨터의 계산 기능에 기반을 둔 새로운 이해와 해석을 제안한다. 본 연구에서는 다양한 계산과학적 문제해결 방법들을 탐색하고, 이를 컴퓨터의 계산적 특성에 따라 분석하였다. 이를 통해 계산과학 문제와 계산과학적 문제해결 방법의 특성을 제시하고, 정보과학의 융합적 성격을 밝힐 수 있을 것이라 기대하기 때문이다.

This paper discusses military diplomacy between middle powers and the UAE. Specifically, eight countries which have been trading with the UAE are selected as middle powers. The purpose of this paper is to find out the effectiveness of military diplomacy among middle powers with the UAE. An economic trade index is the dependent variable, and VIP visits, arms exports to the UAE, officer exchanges for defense education programs, unit stationing, and combined training are the independent variables. There are four independent variables which have meaningful impacts on the dependent variable. However, among them, officer exchanges for defense education programs and combined training have a significant impact on economic trading. Therefore, as a middle power country, the Korean Ministry of Defense should focus more acutely on these two variables for military diplomacy in the future.
